Nobody in Syrjälä understands how the network works. For this reason, if a connection breaks down, nobody will repair it. In this situation a component may be divided into two components.
Your task is to calculate the number of components after each connection breakdown.
The first input line has three integers $n$, $m$ and $k$: the number of computers, connections and breakdowns. The computers are numbered $1,2,\dots,n$.
Then, there are $m$ lines describing the connections. Each line has two integers $a$ and $b$: there is a connection between computers $a$ and $b$. Each connection is between two different computers, and there is at most one connection between two computers.
Finally, there are $k$ lines describing the breakdowns. Each line has two integers $a$ and $b$: the connection between computers $a$ and $b$ breaks down.
After each breakdown, print the number of components.
- $1 \le n \le 10^5$
- $1 \le m \le 2 \cdot 10^5$
- $1 \le k \le m$
- $1 \le a,b \le n$
